Qomolangma — the Most
Dangerous Mountain in the World?
One of the world’s most dangerous sports
is mountain climbing, and
one of the most popular places
for this is the Himalayas. The Himalayas run along the southwestern part of
China. Of all the mountains, Qomolangma
rises
the highest
and is
the most
famous. It is 8,844.43 meters high and so is very dangerous to climb. Thick clouds cover the top and snow can fall very hard. Even more serious difficulties include freezing weather conditions and heavy storms. It is also very hard to
take in
air as you get near the top.
The first people to
reach the top were Tenzing Norgay and Edmund Hillary on May 29,1953. The first Chinese team did so in I960, while the first woman to succeed was Junko Tabei from Japan in 1975.
Why do so many climbers
risk their lives
? One of the main reasons is because people want to
challenge
themselves
in the face of difficulties
.
The spirit of these climbers shows us that we should never
give up
trying to
achieve our dreams
. It also shows that humans can sometimes be stronger than the forces of nature.
Paragraph 1 Spirit of climbers
Paragraph 2 Achievements of climbers
Paragraph 3 Facts and dangers
Paragraph 1
List four dangers for climbers:
thick clouds
Snow slide;
Freezing weather conditions;
Heavy storm;
3b. Read the article again and complete the chart.

List three achievements:
1953 - Tenzing Norgay and Edmund Hillary were the first to reach the top;
1960 - The first Chinese team did so;

Paragraphs 1 & 3
List four comparisons:
most dangerous sport;
most popular places;
the highest mountain;
the most famous mountain
Where are the Himalayas?
2. How high is Qomolangma?
3c. Answer the questions using information from the article.
The Himalayas run along the southwestern
part of China.
It is 8,844.43 meters high.
3. Why do so many people try to climb this mountain even though it is dangerous?
4. What does the spirit of the climbers tell us?
One of the main reasons is because people want
to challenge themselves in the face of difficulties.
The spirit of these climbers shows us that we
should never give up trying to achieve our
dreams. It also shows that humans can sometimes
be stronger than the forces of nature.
